[0025] Refer to Figure 1 , Figure 2 and Figure 5The utility model provides an embodiment: a kind of unmanned aerial vehicle life buoy throwing device, including unmanned aerial vehicle main body 1, unmanned aerial vehicle main body 1 bottom end is connected with fixed plate one 3 by undercarriage 2, fixed plate one 3 inner wall is connected with screw rod 4 by thread sleeve, screw rod 4 is fixedly connected with knob 5 apart from one end, knob 5 outer wall is rotatably connected with moving plate 6, moving plate 6 is rotatably connected with rotating plate 10 apart from one end, rotating plate 10 inner wall is connected with knob 5 by pull rod 11 and clamping block 12, moving plate 6 bottom end is fixedly connected with tenon rod 8, tenon rod 8 outer wall is slidably connected with fixed plate two 9, fixed plate two 9 bottom end is fixedly connected with storage cover 14, storage cover 14 top end is connected with rotating rod 19 by sprocket one 16, chain 17 and sprocket two 18, rotating rod 19 outer wall top side is fixedly connected with baffle two 21, rotating rod 19 outer wall bottom side is fixedly connected with baffle one 20;

[0026] Specifically, before throwing, baffle one 20 is in blocking position, and life buoy main body 22 is blocked in storage cover 14, when motor 15 starts, rotating rod 19 drives baffle one 20 to rotate to the other side, at this time, baffle one 20 cancels the blocking of life buoy main body 22, and the life buoy main body 22 at the bottom end of storage cover 14 falls under the action of gravity, and one throwing is completed, when baffle one 20 rotates, baffle two 21 fixed on the same rotating rod 19 with it also rotates, when baffle one 20 cancels the blocking of life buoy main body 22, baffle two 21 continues to block life buoy main body 22 in storage cover 14 that does not need to be thrown, to prevent it from falling accidentally, when baffle one 20 rotates back to the original position, life buoy main body 22 not being thrown in storage cover 14 falls to baffle one 20 due to gravity, and continues to be blocked, and the operator rotates knob 5, since screw rod 4 is connected with the inner wall of fixed plate one 3 by thread sleeve, the rotation of knob 5 drives screw rod 4 to rotate, under the action of thread sleeve, moving plate 6 rotatably connected with knob 5 moves along the axial direction of screw rod 4, tenon rod 8 fixedly connected at the bottom end of moving plate 6 is originally slidably connected on fixed plate two 9, along with the movement of moving plate 6, tenon rod 8 gradually separates from the groove of fixed plate two 9, so that the whole throwing device can be disassembled from unmanned aerial vehicle main body 1.

[0027] Refer to Figures 2-4The chain wheel one 16 at the top end of the storage sleeve 14 is rotationally connected at the top end of the storage sleeve 14, the outer wall of the chain wheel one 16 is connected with the chain wheel two 18 through the chain 17, the chain wheel two 18 is fixedly connected at the top end of the rotating rod 19, the motor 15 is installed at the top end of the storage sleeve 14 through the fixing frame, the driving end of the motor 15 is fixedly connected at the top end of the left chain wheel two 18, the pull rod 11 at the inner wall of the rotating plate 10, the pull rod 11 is fixedly connected with the clamping block 12 at the rear end, the clamping block 12 is slidingly connected at the apart one end of the knob 5, the outer wall of the pull rod 11 is provided with the spring 13, one end of the spring 13 is connected at the inner wall of the rotating plate 10, the other end of the spring 13 is connected at the apart one end of the clamping block 12, the bottom end of the unmanned aerial vehicle main body 1 is fixedly connected with the bottom frame 2, the bottom frame 2 is fixedly connected at the top end of the fixed plate one 3, the moving plate 6 is fixedly connected with the limiting rod 7 at the close one end, the limiting rod 7 is slidingly connected at the inner wall of the fixed plate one 3, the top end of the baffle one 20 and the baffle two 21 is provided with the life buoy main body 22;

[0028] Specifically, the driving end of the motor 15 drives the chain wheel one 16 to start rotating, since the chain wheel one 16 and the chain wheel two 18 are connected through the chain 17, the rotation of the chain wheel one 16 will drive the chain wheel two 18 to rotate synchronously through the chain 17, and the chain wheel two 18 is fixedly connected at the top end of the rotating rod 19, so when the chain wheel two 18 rotates, the rotating rod 19 will also rotate, the operator pulls the pull rod 11 at the inner wall of the rotating plate 10, the clamping block 12 fixedly connected at the rear end of the pull rod 11 is originally slidingly connected at the apart one end of the knob 5, and plays a limiting role, when the pull rod 11 is pulled, the clamping block 12 moves, and the limiting of the knob 5 is cancelled.

[0029] Working principle: when the unmanned aerial vehicle main body 1 needs to drop the life buoy main body 22, the motor 15 drives the left side sprocket two 18 to rotate, and under the action of the chain 17 and the sprocket one 16, the right side sprocket two 18 is driven to rotate, thereby driving the baffle one 20 and the baffle two 21 on the rotating rod 19 to rotate, the baffle one 20 will block the life buoy main body 22 in the storage sleeve 14 before dropping, when the motor 15 starts, the baffle one 20 will be rotated to the other side to cancel the blocking of the life buoy main body 22, so that the bottommost life buoy main body 22 is dropped, the baffle two 21 will be driven at the same time when the baffle one 20 rotates, so when the baffle one 20 cancels the blocking of the life buoy main body 22, the baffle two 21 will continue to block the life buoy main body 22 which does not need to be dropped, when the baffle one 20 rotates back to the original position, the life buoy which is not dropped will fall on the baffle one 20 due to gravity and continue to be blocked, when the subsequent needs to disassemble the dropping device from the unmanned aerial vehicle main body 1, pull the pull rod 11 to drive the clamping block 12 to cancel the limiting of the knob 5, prevent the lead screw 4 from rotating accidentally when it is in a stationary state, thereby enhancing the locking between the lead screw 4 and the fixed plate, then rotate the knob 5, under the action of the threaded sleeve, the moving plate 6 can be moved, thereby making the tenon rod 8 separate from the groove in the fixed plate two 9, and then the dropping device can be disassembled from the unmanned aerial vehicle main body 1.

[0030] Finally, it should be pointed out that: the above only for preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
